Abstract
The results of correcting the readings of DVGN-01 albedo dosimeters behind the shielding of the MC400 cyclotron at the Laboratory of Nuclear Reactions (LNR) with the use of the spherical albedo system are presented. The formulas approximating the dependences of correction coefficients used to correct the readings on the hardness parameters of low-energy neutron spectra were obtained based on these results and the results of earlier studies. Neutron spectra were measured at three points behind the MC400 shielding, and the correction coefficients for DVGN-01 were calculated based on these spectra. It was demonstrated that these coefficients agree well with the coefficients obtained with the use of the spherical albedo system. This suggests that the obtained correction coefficient values are accurate. The recommended correction coefficient values to be used in the individual dosimetric control at LNR were specified based on the results of the present study and the data given in other papers.
